Definitions
- the subject of the invention is a compact material "repulpable” and water resistant, obtained from crushed cellulosic materials.
- compact material is meant, at sense of the present invention, a material having a sufficient cohesion and mechanical strength to be able to be used for example in the industry of furniture, in the construction industry (for example example for the manufacture of panels or partitions), in the horticultural industry (e.g. for manufacturing trays for potted plants) or in the packaging (for example for manufacturing pallets, supporting elements, shims, elements spacing ).
- plumbable is meant, always within the meaning of the present invention, the property which the can be used directly after a possible grinding, as a raw material in manufacturing paper, without requiring any sorting or physical, mechanical, or physico-chemical separation, and without generate waste other than waste normally produced during the production of paper. Such a material repulpable can therefore be introduced directly at the pulp from the paper machine, without sorting operation prior.
- the invention consists in selecting, for the manufacture of the compact materials according to the invention, products which prove compatible with this property of total repulpability.
- binding agents are selected on the one hand, and agents capable of imparting some resistance to water on the other hand, which are perfectly compatible with said repulpability property.
- binding agents is necessary in order to allow the production of compact materials with a sufficient strength and cohesion, in particular high compressive and flexural strengths.
- the presence of agents capable of imparting some water resistance is desirable because the compact materials targeted by the invention can be used in very humid atmospheres, or be placed in contact with damp soil.
- binders such as alcohols polyvinyl and their derivatives, celluloses and their derivatives, lignosulfonates, starches and their derivatives, alkali silicates, clays, tars, pitches and bitumens have already been offered.
- the effective quantity is the quantity sufficient to achieve the desired effect.
- the organic binder is chosen from starches, starch derivatives, and / or starch or starch by-products.
- the organic binder is chosen among native starches, possibly made soluble in cold water using physical treatment of baking-extrusion and / or gelatinization on a drum.
- waste water is used deprotein from a starch protein factory, particular potato starch.
- Water deproteinized waste in question can be obtained in various ways, and in particular to result from potato starch effluent treatment known to those skilled in the art as “water from vegetation "or” red water “, the general principle of which production is described in French patent FR 2 256 727.
- the water-resistance agent is chosen from organosilicon water-repellants, the structural unit of which corresponds to the formula: in which R and R 1 , which may be the same or different from each other, are hydrogen or organic radicals chosen from the group comprising methyl, alkyl, fluoroalkyl, optionally substituted phenyl, vinyl or their derivatives chlorinated, alkoxy, alkyllamino, said compound being advantageously chosen from the group comprising non-reactive silicone oils, silicone resins, reactive silicone oils, especially hydroxylated, alkylated, arylated, hydroalkylated, hydroarylated as well as mixtures of these products and the emulsions which can be prepared from these products.
- organosilicon water-repellants the structural unit of which corresponds to the formula: in which R and R 1 , which may be the same or different from each other, are hydrogen or organic radicals chosen from the group comprising methyl, alkyl, fluoroalkyl, optionally substituted phen
- the water-repellent agent is chosen from copolymers fluorinated products such as those sold by ELF ATOCHEM under the name FORAPERLE, and in particular under the name FORAPERLE 321.
- the proportion of water repellent is, ultimately, calculated to give the compact material a hold satisfactory water, knowing that the main objective by the invention is to ensure the repulpability of the material got.
- the compact material according to the invention can possibly include other constituents such as by example of hardening agents, present in a proportion from 0.5 to 25%, preferably from 1 to 5% by weight relative to by weight of crushed cellulosic materials.
- the curing agents in question may be selected from the group of alkaline agents, plus particularly in the group of hydroxides and oxides of alkali or alkaline earth metals, or in the group of salts of strong bases or weak bases, and in particular among carbonates of alkali or alkaline earth metals.
- the preferred hardening agent is lime hydrated.
- the compact material according to the invention can also include other constituents such as, for example, bactericides, fungicides, rat poisons ...
- the water-repellent agent is therefore distributed in the heart of the compact material, which allows to obtain excellent water resistance.
- this water resistance can be further enhanced by applying an additional amount of water repellent on the surface of the compact material already formed, by any known technique, for example by coating, impregnation, immersion, spraying or brushing.
- a composition of matter comprising the organic binder and minus part of the water repellent.
- the nature and proportions of the constituents are selected in such a way that the compact material obtained has characteristics of mechanical resistance, water resistance and repulpability indicated previously.
- the compact material obtained is subjected at the end of the shaping treatment to a treatment steaming under generally temperature conditions between about 80-100 ° C and about 200-220 ° C.
- the duration of this parboiling treatment depends on the temperature, but is usually between 15 minutes and 5 hours, preferably between 30 minutes and 3 hours.
- this parboiling treatment is optional and does not constitute essential step of the process which is the subject of the invention.
- compact materials according to the present invention present in this case, by simple treatment with ambient temperature, the required physical characteristics and in particular a high mechanical resistance; steaming does not only accelerates the drying of compact materials obtained.
- the compact material according to the invention has variable mechanical characteristics depending on the pressure which is exercised during the shaping treatment.
- a "mattress" made of cellulosic materials which is flexible and elastic.
- Such a material may be suitable for example in calibration operations or as a product anti-shock or anti-vibration.
- the compact material obtained has resistance to very high bending, tensile and compression and can be advantageously used as a cushioning material, or as a reel core. He can also serve as material for making pallets biodegradable and plumpable. This is an advantage essential of the present invention.
- Another essential advantage of the present invention is that by selecting binding agents and water repellents including contact with food food is allowed, we can get materials compacts that can be used for example as cushioning materials in product packaging food or as a packing material for packaging of toys, for example.
- test pieces are then placed in an atmosphere humid, at 100% relative humidity and at 25 ° C. He is not observed disintegration, even after several weeks. The mechanical strength of test pieces remains unchanged after this stay in wet storage. The interior of the test specimens does shows no trace of moisture.
- test pieces then being placed in an atmosphere humid, at 100% relative humidity and at 25 ° C, swelling of the platelets after 24 hours. After 96h, the material no longer has any cohesion.
- test pieces being placed in a humid atmosphere, at 100% relative humidity and at 25 ° C, there is a swelling of platelets after 24h. After 72 hours, the material no longer has any cohesion.
- This example shows that the addition of 10% of AGGLOFROID R 009 and 3% of potassium siliconate by dry weight relative to the weight of paper waste makes it possible to obtain compact materials satisfying the requirements of the technique, namely having sufficient mechanical resistance and resistance to humidity while remaining plumpable in a stationery pulper.
- test pieces thus obtained have a cohesion to green sufficient to undergo transport.
- test pieces After drying for 72 hours at room temperature, the test pieces are immersed in a siliconate solution 10% potassium.
- test pieces absorb 5% of said solution. After drying at room temperature, they have a "beading" effect, that is to say a repellent effect vis-à-vis water, very marked.
- test pieces are then placed in an atmosphere humid, at 100% relative humidity and at 25 ° C. Any disintegration is not observed, even after several weeks. The mechanical strengths of these test pieces remain unchanged after this stay in a humid atmosphere. Likewise, the "sparkling" effect is preserved.
- test tube if an entire test tube is placed in cold water with stirring, it begins to disintegrate after 4 to 5h. If this plate is broken in several pieces before being placed in water, we get, after only two hours, a coarse pulp, sufficiently dispersed to be subjected to the work of a stationery disintegrator.
- a mixer of the Robot coupe type 500 g of paper waste having a particle size less than 2 mm and 500 g of paper waste having a particle size between 1 cm and 2 cm are introduced on the one hand, and on the other hand share, 200 g of a modified corn starch glue sold by the company ROQUETTE FRERES under the name AMILYS R 100, the dry matter of this glue being 35% by weight.
- the mixture is kneaded for 5 minutes and then 20 g of water-repellent product sold under the name HYDROFUGE 68 by RHONE POULENC are added.
- the mixture is agglomerated by molding in the form of rectangles 30 cm long, 12 cm wide, and 2 cm thick, under a pressure of 3432 10 4 pascals.
- the samples thus obtained have a very high green cohesion, allowing all useful manipulations.
- test pieces are then placed in an atmosphere humid, at 100% relative humidity and at 25 ° C. Any disintegration is not observed, even after several weeks.
- the mechanical resistance of the test pieces remains unchanged after this stay in a humid atmosphere.
- the interior of test pieces show no trace at observation humidity.
- test tube is placed in a beaker of cold water with gentle stirring for 4 to 5 hours, observe that the test tube begins to swell slightly and then that it disintegrates. After 6 to 7 hours, a paste is obtained. coarse paper, sufficient to be worked in a stationery refiner.
- test pieces are then placed in an atmosphere humid at 100% relative humidity and at 25 ° C. There is a swelling of these test tubes after only 24 hours. After 96h, the compact material thus obtained no longer has no cohesion.
- test pieces are placed in a humid atmosphere at 100% relative humidity and at 25 ° C. There is a swelling of these test tubes after 96 hours. After 144 hours, these test pieces have only a weak cohesion.
- Test tubes prepared under the same conditions that in example 4 above, are immersed in a FORAPERLE 321 solution at 50%. We see that the test tubes absorb 10% of the solution. After drying at room temperature, they have a slight effect "beading". However, after drying for 2 hours at 120 ° C, we notes that the "beading" effect obtained is very marked.
- Test pieces prepared under the same conditions as in Example 4 above, are immersed in a solution of pregelatinized potato starch with 5% dry matter, mixed with 20% calcium carbonate and 10% of FORAPERLE R 321. The test pieces thus absorb 5% of the solution. After drying at room temperature, these test pieces show practically no "beading" effect. On the other hand, after drying at 120 ° C for 2 hours, the "beading" effect is very marked.
